It's Sky encouraging us to reduce our carbon footprint. It only happens after a certain time at night if you haven't used your remote control for X amount of time. You can change it if you like though, if I remember correctly, the option is in the system setup.
I set the timer on my DVD recorder to record a programme at 2 AM this morning, and all I got was a message that my digibox was about to go ino standby.
As Lakitu says, go into Services and there is an option to cancel it if you wish.
I do turn my digibox off overnight when not recording something, and actually doubt if it uses much leccy anyway.

A Sky+ box would get round this problem as you can record to the hard disk in the Sky+ box.
Once you have watched it you can delete it if you dont want it, or copy it to DVD if you DO want to keep it.
